无法将结构体数据存入链表中

使用vs2019

#include <stdio.h>
#include<string>
#include <stdlib.h>
#include <conio.h>
#define OK 1
#define ERROR 0
#define OVERFLOW -2
#define MAXSIZE 1000
typedef int Status;

typedef struct {
    int no;
    char name[50]; //book's name
    float price;
}Book;
typedef struct {
    Book* elem;
    int length;
}SqList;
Status InitList(SqList& L)
{
    L.elem = new Book[MAXSIZE];
    L.length = 0;
    return OK;
}
Status ListInsert(SqList& L, int i, Book book) {
    if (i<1 || i>L.length + 1)
        return ERROR;
    if (L.length == MAXSIZE)
        return ERROR;
    for (int j = L.length - 1; j > i - 1; j--) {
        L.elem[j + 1] = L.elem[j];
    }
    L.elem[i - 1] = book;
    ++L.length;
    return OK;
}
Book SetBook() {
    Book book;
    int no=0;
    char name[50]="";
    float price=0.0;
    printf("请输入no:\n请输入书名:\n请输入价格:\n");
    scanf_s("%d", &book.no);
    scanf_s("%s", &book.name,50);
    scanf_s("%f", &book.price);
    return book;
}
int main(){
    SqList L;
    InitList(L);
    Book book=SetBook();
    ListInsert(L, 2, book);
    printf("%d", L.elem[2].no);
    return 0;
}

调试的时候book能够得到我输入的值，但是到了ListInsert函数中，book没有赋值给L.elem[i-1],求大佬解答
